YOKIE. FOR DRAFT-RIGGINGS.

Application filed July 6, 1915,

To all whom it may concern:

Be it known that I, JOHN R. MITCHELL,

a citizen of the United States, residing at ployed to securely unite thehood or head with the yoke strap.

In the drawing forming a part of this specification, Figure 1 is a partsection, part side elevation of a yoke showing one embodiment of myinvention. Fig. 2 is a trans- I verse vertical section taken on the line2-2 of Fig. 1. Fi s. 3 and 4 are views similar to Fig. 1, butillustrating difi'erent methods of carrying out my invention, in each ofsaid figures the rear portion of the strap being hroken oif.

In said drawing referring to Figs. 1 and 2, A denotes the hollowsubstantially rectangular head or hood within which is adapted to bereceived the butt of a draw bar 10. In the construction shown, the hoodand draw bar are connected by means of a coupler key 11, the latterextending through slots in the side-walls 12-12 of the hood. At the topand bottom, the hood or head A is provided with longitudinally arrangedslots 13--13, each having a plurality of ofi'set portions 1414 and acorresponding number of depressions or grooves 1515, the latter aliningwith perforations 16 in the sldes of the hood.

The yoke strap is designated by the reference B, the same being ofsubstantially U shape and having upper and lower arms 17 and 18, theouter ends 19-19 of which are positioned within the slots 13-43.

In manufacturing my improved yoke, the hood A is formed with the slots13, grooves 15 and perforations 16, as shown. The ends of the strap Bare preferably heated and inserted within the slots of-the. hoodwhereupon the pins or rivets 2020 are driven through the lperforations16 and recesses 15, thereby lisp acing the metal of the ends 19Specification of Letters Patent.

to fill the ofi'set portions 14, as indicated at 21 -21. The connectionbetween the strap and the hood thus provided is strong and prevents thehood being pulled .ofi of the strap under load.

In the modification shown in Fig. 3, the hood A is provided with upperand lower slots 113, each of said slots having merely a. single offsetor depression 114, and only one P111 120 being used to secure the ends119 of the yoke strap.

In Fig. 4, the structure there illustrated comprises a hood or head Ahaving upper and lower slots 213, each of the latter having two oflsetsor depressions 214 oppositely arranged, that is, one on one side of theslot and the other on the opposite side thereof. Recesses 215 to receivethe pins 220 are provided, one opposite each ofiset 214. The pins 220are applied in the same manner as the pins 15, with the result that theends 219 of t e yoke strap are bent or displaced so as to form an ogeecurve.

From the preceding description it will be seen that in each instance themeans of connecting the hood and strap involves the odsetting ordisplacement of portions of the yoke strap, these portions of the strapbeing forced into corresponding ofisets or depressions in the walls ofthe slots in the hood. Also, corresponding to each ofiset or depressionin the slots of the hood are ribs or projections, either integral orremovable, by which the offsetting of the metal of the straps isaccomplished. In each modification it is furthermore evident that atortuous passage is formed in the hood to receive a. correspondinglyshaped section of metal forming the ends of the strap, therebypreventing the separation of the strap and hood under tension.

One of the advantages of my improved arrangement lies in the fact thatthe connection between the strap and the hood is made without removingor losing any of the metal of the strap, such as is necessary whererivets to pierce the strap are employed. In other words, my improvedstructure always retains the full, efi'ective strength of t e strap.

I claim:

1. A yoke for draft riggings comprising, a hollow head having slotsextending longitudinally therethrough and a. strap having the endsthereof seated in said slots, said slots being so formed as to providereversely curved passage ways and the ends of the strap being bent toconform to said reversely curved passage Ways.

2. A yoke for railway draft riggings comprising, a hood adapted to besecured to a draw. bar, said hood having longitudinally arranged slotsthrough the top and bottom Walls thereof, each of said slots beingoffset 10 intermediate its ends, a strap having the ends thereof seatedin said slots and bent to conform to the offset portions of said slots,and pins extending transversely through the head and engaging saidstraps on the inner sides of said offset portions thereof.

In witness that I 'claim the foregoing I have hereunto subscribed myname this 30th day of June, 1915.

- JOHN R. LflTCHELL.
